Slashes in filenames on Google Drive External storage causes sync error

[moretocome]

The title says it all. Whenever someone creates a document on Google Docs that contains a slash / in the filename, it causes a sync-error in my Nextcloud client. I expect other illegal characters could also produce the same error, but I have only experienced it with slashes.

Login into Drive and changing the file name fixes the error, but maybe some type of escape function should be implemented for illegal file name characters.

NC and External app are both most recent stable versions and the server is a RPI with the latest Raspbian.

Steps to reproduce

1. Enable External Sites App
2. Add Google Drive to Nextcloud
3. Create a document in Google Docs

Expected behaviour

The file from Google Drive should sync with Nextcloud

Actual behaviour

The file produces a continuous sync error in the Nextcloud Client

I have a related problem: For folders with slashes in their name, only the part after the slash is shown and the folder can not be accessed in any way.

Sounds like the same issue.

Also getting the same issue with any file within Google Drive that contains "/". Will happily post any logs etc that are required if needed.
